The PFAS Question: What Tighter Rules Mean for PTFE-Fortified Lubricants
Regulators in the US and Europe are closing in on PFAS. Here is what that means for the PTFE greases and oils on your maintenance shelf, and how to plan ahead.
For decades, PTFE has been one of the most useful solid additives in specialty lubrication. A few percent of sub-micron PTFE powder lowers friction, smooths out surface imperfections and helps a grease hold up under load. It shows up in food-grade greases, thread sealants, chain oils and aerosol dry-film lubricants.
PTFE is also a fluoropolymer, which puts it inside the broad family of chemicals known as PFAS (per- and polyfluoroalkyl substances). That is why maintenance and purchasing teams are starting to get questions about it from their EHS departments.
What is changing
In Europe, the European Chemicals Agency (ECHA) is evaluating a broad restriction on PFAS under the REACH regulation. The proposal covers thousands of substances across many industries, and lubricants are one of the sectors under review. The final scope, the exemptions and the transition periods are still being worked out.
In the United States, the EPA has a one-time reporting rule under the Toxic Substances Control Act (TSCA Section 8(a)(7)). It requires companies that manufactured or imported PFAS, including PFAS in some products, to report use and exposure data. The reporting window has already been pushed back more than once, so check the current EPA timeline if you import lubricants directly.
At the state level, Minnesota and Maine have passed laws that phase out products with intentionally added PFAS, and other states are following. Most of these laws target consumer products first and give industrial users longer timelines. Even so, they are pushing manufacturers to develop PFAS-free options now.
What this means on the plant floor
Nothing changes overnight. PTFE-containing lubricants are legal to buy and use in the US, the EU and Türkiye today, and many applications have no drop-in replacement yet. The practical risk is procurement disruption later: a product you rely on could be reformulated, relabeled or discontinued as regulations take effect.
A few steps make sense now:
- Inventory your PTFE products. List every grease, oil, paste and aerosol in your plant that contains PTFE, and where it is used. Your supplier’s data sheets will tell you.
- Separate critical points from convenient ones. Some applications really need PTFE’s low friction. Others use a PTFE product only because it was on the shelf.
- Test alternatives before you have to. Molybdenum disulfide (moly), graphite, hexagonal boron nitride and calcium sulfonate complex greases can cover many applications that currently use PTFE. Running a trial on non-critical equipment now is far cheaper than an emergency switch later.
- Keep documentation current. Customers and auditors are starting to ask about PFAS in supply chains. Up-to-date SDS and product data sheets make those conversations short.
How we can help
Oilsan carries both PTFE-fortified products, such as HUSKEY™ TF-1000 and HTL-500, and PTFE-free options built on moly, graphite, silicone and synthetic bases. If you want a second opinion on which of your lubrication points could switch, send us your list. We will match each point to the right product and send samples for testing.
